Ocean Currents/Influences on Climate Test

What is energy from the sun that reaches the Earth?

• thermohaline
• solar radiation
• convection

What is the difference between climate and weather?

• Weather is the condition of the atmosphere over a long period of time; climate is the condition of the atmosphere at a specific time and place.
• Weather is the daily condition of the atmosphere at a specific time and place; climate is the average weather patterns over a long period of time.
• Weather is easy to figure out; Climate is much harder to figure out.

What is an area's distance north or south of the equator called?

• longitude
• equatorial
• latitude

What is the driving force behind our weather?

• convection currents
• ocean currents
• the Sun (differences in temperatures)

Which of the following is NOT a way oceans affect Earth's climate?

• Oceans have cold and warm currents that can influence the climate of places near them.
• Oceans absorb the sun's energy, store it, and release it.
• Oceans reflect most of the Sun's solar radiation back into space.

What is heat transfer from rising, hotter, less dense fluids and falling, cooler, denser fluids?

• convection
• radiation
• conduction

How do differences in density cause convection currents?

• Less dense water and air sink, and more dense water and air sink.
• Less dense water and air rise, and more dense water and air sink.
• Less dense water and air sink, and more dense water and air rise.

What type of currents are caused by the steady winds over the surface of the ocean?

• surface currents
• deep currents
• Coriolis currents

What is the motion of ocean water in one direction?

• salinity
• ocean currents
• convection

What type of currents are caused by density variations due to temperature and salinity differences?

• surface currents
• deep currents
• Coriolis currents
